To all whom it may concern:

Be it known that 1, JOHN IRVIN Yonnn,

a citizen of the United States, residing at Ashland, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Antiskidding Devices for Motor-Vehicle Wheels, of which the following is a specification, reference being had to the accompanying drawings. I

This invention relates to an improved anti-skidding device for motor vehicle wheels and has forits primary object to provide a device of the chain tread type which is so constructed that the transverse chains may readily move or shift upon the tread of the wheel tire so that the tire will be evenly worn by said chains.

It is another important object of the invention to provide simple and effective means for retaining the transverse tread reducing to a minimum the possibility of the breakage of said chains.

It is also one of the more particular obfleets of the invention to devise improved fastening or retaining means for the chains, which is so constructed as to admit oi? the easy and quick removal of any one more of the chains or the adjustment of the same circumferentially of the wheel tire, and to also provide easily actuated means for tightening the transverse chains upon the periphery oi the tire.

lit isa further object the invention to generally improve and simpliry the construction of anti-skidding .clevices of the above type, whereby thesame rendered highly etiicient and serv ceable in practical use, strong and durable in constrnction, and capable of manufacture relatively small cost.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrange ment of parts to be hereinalter more fully described, claimed and illustrated in the accompanying drawing, in which, a

Figure l is a partial outer side elevation, of a wheel having my improved anti-skid ding means applied thereto;

Fig. 2 is a similar view looking at the inner face or the wheel;

Fig. 3 is an enlarged transverse section taken on lin f Fig. 4: is an enlarged fragmentary perspective view of the device; and

Figs. 5 and 6 are detail perspective views of the chain attaching arms.

Referring in detail to the drawing, 5 designates a motor vehicle wheel which is equipped in any usual or approved manner with a suitable tire 6. This tire may either be of solid rubber construction or of the inflatable pneumatic type.

My invention, in its preferred form, includes a flat, metal ring made up of two sections indicated at 7. These sections are rigidly connected to each other at one of their ends by means of plates 8 engaged upon the opposite side faces of the ring sections and securely riveted to one of said ring sections, as at 9. The plates 8 are loosely connected to the opposed end of the other ring section by the spaced pins indicated at it) inserted through coinciding openings and plates and detachably held therein by cotter pins ll oi equivalent means. The ring or annulus thus formed is adapted to be arranged upon the inner side of the vehicle wheel.

- A second ring or annulus is adapted to be arranged u on the outer side of the vehicle wheel and this ring also consists oi two semicircular sections 12, each of which consists of a rod, and the opposed ends of said ring sections are threaded in relatively opposite directions as at 13. The ring sections are connected by the turn buckles 14, the bores of which are provided. with right and left hand threads in their opposite ends to receive the correspondingly threaded ends of the ring sections 1%.

.Each of the flat, metal ring sections 17 is provided with a plurality of equidistantly spaced openings 15, and upon these ring sections the bifurcated ends it? of the longitudinally curved arms 16 are adapted to be engaged. The spaced portions of the bifurcations l'l are perforated to coincide with one or the openings 15 in the metal ring and loosely receive a bolt 18 upon the outer end of which a retaining nut 19 is threaded. A similar series'of curved arms 20 are engaged upon the other ring sections 12, each of the latter arms having a sleeve 21 formed upon one its ends loosely engaged upon said ring. The arms 15 and 20 are longitudinally curved to extend inwardly over the outer races oi the side flanges on the tire relation to the wheel.

The outer ends of the arms 16 and 20 are perforated to-receive the terminal -links of the tire chains 22 which extend transversely across the periphery of the tire 6. In'the large majority of cases-these chains upon antl-skidding devices as now constructed, break because of their wearing contact upon the side flan es of the wheel rim,- and it is z to be particu arly observed that, in the present invention,"no portion of these chains en-, gages any metallic part, but they are wholly disposed upon the rubberftire,

From thefo-regoing description, taken in connection with the accompanying drawing, theconstruction, manner of operation and several advanta es of the invention will be clearly and -ful y understood. The several may be easily andparts of the inventionquickly assembled and arranged in proper As the arms 20 are slidably engaged upon the ring sections 12, they may readily shift thereon so that the transverse tread chains will move upon the periphery of the tire and not wear at all times in one place. The said chains may also be tightened to exert greater or less pressure upon the periphery of the tire by the proper adjustment of the turn buckles 14 connecting the ring sections 12. .Any one or' m'ore of the chains may also be readily replaced or removed by simply removing the bolts 18 and detaching the inner arms 20. It is also to be observed that in caseone or more of these transverse chains break, it will invention as claimed.

or destroy; their," continue the operation of the device. I manifest that thefin-vention is extremely durable and,- in view of the simple form and construction of; the several elements, any

part thereof, may be 'readily replacedat nominal cost.

., While I have shown and des cribed the preferred construction and arrangement of the several elements, it is to be understood thalt1 I reserve the privilege of adopting all suc embodied within the spirit and scope 'of the Having thus fully described my invention, whatI desire to claim and secure by Letters Patent is 1 An anti-skidding including ranged upon opposite sides of a wheel felly, a series of spaced arms detachabl secured upon one of the rings and held agzginst relatlve shifting movement, a series f spaced device for wheel tires metalrings adapted to be arlegitimate changes vas maybe fairly 1 arms mounted on the other ring for free cir
